According to a method for producing a stent which is formed into a tubular body and includes at least one marker formed from a marker housing and a marker insert including: using an indenter having a partially spherical shaped distal end, the distal end coming into contact with the marker insert when the marker insert is pressed with the indenter and is pressure fitted to an opening provided on the marker housing to fix it thereon, a sufficient load can be applied to a radiopaque marker insert when the marker insert is attached to the stent, and further a stent having a radiopaque marker whose marker housing has little damage can be produced.

Stent, method for producing same and device for producing same

A method for producing an in-vivo indwelling member includes a step of winding a metal wire () to form a primary coil (-), a step of giving the primary coil (-) a shape to form a secondary coil (-), and a step of inserting the secondary coil (-) into an inner hollow section () of a shaping mold (). The secondary coil (-) includes different patterns such as a helical shape (--), a linear shape (), and a circular arc shape (-). When the secondary coil (-) is pushed into the inner hollow section (), the secondary coil (-) makes contact with the inner wall surface of the inner hollow section (), and a portion between different patterns is randomly curved. Accordingly, the in-vivo indwelling member has a three-dimensional structure that corresponds to the shape of the inner hollow section (). The in-vivo indwelling member is less likely to deviate from the inside of an aneurysm when released into the aneurysm.
